Plenty of calendars fill your day. This one shows what's left: your events subtracted from your waking hours, on the home screen. No manual needed.
A calendar that opens on one number: how many hours of today are still yours.
A calendar tells you which hours are taken. What you actually want to know is the opposite.
■ Your free time, on the home screen
Take the hours you're awake. Subtract what's ahead of you.
"Bed at 11. It's 7 now. One hour booked at 9."
— three hours left.
That number is the first thing you see when you open the app. Add an event and it drops, right there.
■ No manual
Long-press to add an event.
Drag to move it.
Swipe to delete it.
Every year you've spent with a phone is the only instruction manual you need.
"It probably works like this…"
— and your instinct is always right.
■ What that time is being traded for
Add a shift and your pay is worked out from your hourly rate, including night, overtime and holiday premiums. You can see what your free time turned into.
■ Also
• One tap between month and week view
• Drag across the week view to create; drag an event to move it
• Colour-code your events and read the month at a glance
• Attach photos to events and look back on them
• A lock-screen widget for today's free time
• Your events, tasks and photos stay on your device. No account required
Build your day, your way.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New
- The planning agent can now delete events, too — just write something like “delete the economics lecture” or “delete everything this week” and matching events are removed
- Name a date or weekday to limit it to that range; leave it unspecified and past occurrences are cleared too (say “from now on” to limit it to today onward)
